New Tech Converts CO2 Into Electricity And Hydrogen

Amid increasingly urgent calls for more radical climate change action, a team of South Korean scientists has found a way to kill two birds with one stone by converting carbon dioxide into electricity and hydrogen. The team, from the Ulsan National Institute of Science and Technology, took as a starting point of their research the fact that when CO2 is absorbed into the sea—which is where most CO2 emissions end up—the acidity levels of the water rise. As per their report , “If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2.” The system that the researchers invented very much resembles a fuel cell in which the reaction starts when CO2 is injected into the water, which contains the catalyst necessary for the reaction and […]
